I'm using V5R6, and after unzipped & saved the *.CATPart file, and opened Catia, I tried to OPEN the file saved already, but CATIA closed itself.
...the *.zip done with V5R6 (see...Telechargement)
...if I double click on the *.CATPart file, Catia try to open and again disappear ...
Thanks for help and your time,
Daniel Attitude is everything!
